This 20-bit bus-interface D-type latch is designed for
1.65-V to 3.6-V VCC operation.
The SN74ALVCH16841
features
3-state
outputs
designed specifically for driving highly capacitive or
relatively
low-impedance
loads.
This
device
is
particularly suitable for implementing buffer registers,
unidirectional bus drivers, and working registers.
The SN74ALVCH16841 can be used as two 10-bit
latches or one 20-bit latch. The 20 latches are
transparent
D-type
latches.
The
device
has
noninverting data (D) inputs and provides true data at
its outputs. While the latch-enable (1LE or 2LE) input
is high, the Q outputs of the corresponding 10-bit
latch follow the D inputs. When LE is taken low, the Q
outputs are latched at the levels set up at the D
inputs.
in either a normal logic state (high or low logic levels) or the high-impedance state. In the high-impedance state,
the outputs neither load nor drive the bus lines significantly.
OE does not affect the internal operation of the latches. Old data can be retained or new data can be entered
while the outputs are in the high-impedance state.
To ensure the high-impedance state during power up or power down, OE should be tied to VCC through a pullup
resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.
Active bus-hold circuitry is provided to hold unused or floating data inputs at a valid logic level.
The SN74ALVCH16841 is characterized for operation from -40
°C to 85°C.
